Thank you all for your suggestions. I'm somewhat troubled though. Electronics is a very dynamic subject, with plenty of people working on it, with fast exponential growth over an incredibly long period and with an enormous impact on our society. Yet, almost all of the references you have suggested are from the
1950's or even older.I'm not saying they aren't good, but they are, well, dated. I suppose analog electronics is a mature subject, sort of like plumbing, or carpentry. I didn't see it like that, but now I wonder.
